Description

Technical Field

[0002] In modern railway construction, track covers, as an important part of the track structure, are mainly responsible for protecting the track, preventing foreign objects from intruding, and ensuring driving safety. In recent years, with the deepening of the concept of sustainable development and the enhancement of environmental awareness, recycled aggregate high-performance concrete, as a green building material, has been widely used in the field of construction engineering. Recycled aggregate is the aggregate obtained by crushing, screening and other processes of construction waste such as waste concrete and bricks. It has significant advantages such as low cost, resource utilization and environmental protection. Applying recycled aggregate to the design of track covers can not only realize the recycling of construction waste and reduce pollution to the environment, but also alleviate the problem of shortage of natural aggregate resources to a certain extent. Using recycled aggregate high-performance concrete (RAC) as the material of track covers can make full use of construction waste resources while meeting the performance requirements of track covers.

[0003] However, the design of traditional track covers is often limited to its protective function, with relatively simple functions, and it is difficult to adapt to the increasingly complex needs of railway engineering. In particular, when railway engineering vehicles need to cross the tracks for operation or maintenance, traditional covers cannot provide convenient passages, resulting in low construction efficiency and safety hazards.

[0004] At the same time, the existing track cover prefabrication device has high manual participation, low efficiency, and its surface is prone to unevenness due to the characteristics of recycled aggregate. Based on the above problems, how to design a highly functional recycled aggregate concrete track cover and its efficient prefabrication device is particularly important.

[0019] The present invention also provides a prefabrication process of a recycled aggregate high-performance concrete track cover, comprising the following steps:

[0020] S1, mold adjustment operation;

[0021] According to the required size of the track cover, the rotation parameters of the external driving mechanism are adjusted to drive the driving gear to rotate, and the driving gear meshes with the opposite racks on both sides, so that the two opposite racks move in opposite directions, and the opposite racks drive the linkage rod to move, and the linkage rod pulls the molding block to move on the interlaced through groove, and the molding block drives the second inclined surface to move, squeezes the internal space of the prefabricated groove, so that the long size of the cross ramp part can be controlled, so that the appropriate size can be selected according to production needs;

[0022] S2, operation to enhance structural strength;

[0023] When the driving gear rotates, it drives the rotating cylinder at its top to rotate, and the curved groove on the outer wall of the rotating cylinder is slidably sleeved on the limit rod. Therefore, when the rotating cylinder rotates, due to the cooperation of the curved groove and the limit rod, the rotating cylinder rotates and moves upward as a whole, and the rotating cylinder pushes up to drive the annular groove and the top extension rod to move upward. The top extension rod moves upward and is inserted into an axial hole vertical to the double-axial holes. The top extension rod squeezes the support rod, and the contact surfaces of the top extension rod and the support rod are both in the shape of a hemispherical head. The support rod is movably inserted into an axial hole horizontal to the double-axial holes. The movement of the support rod drives the compression plate to move, and the compression plate slides in the limit groove to squeeze the spring. The other end of the support rod extends out of the row and hanging block to form a bulge. After the recycled aggregate high-performance concrete is poured, when the steel frame is placed in it for solidification and fixation, the raised support rod gives the steel frame a supporting force to prevent the steel frame from sinking to the bottom.

[0024] S3, recycled aggregate concrete pouring operation;

[0026] S4, surface treatment operation;

[0027] After the recycled aggregate high-performance concrete raw materials are poured into the cover plate prefabricated mold, the surface treatment mechanism is driven to move downward through the vertical moving mechanism, driving the servo motor to rotate, and the servo motor drives the rotating disk A to rotate. The rotating disk A pulls the belt to drive the rotating disk B to rotate through the connecting rod. The rotating rod on the rotating disk B pulls the guide block to slide back and forth in the guide rail, driving the flipping assembly to scrape the top surface of the cover plate prefabricated mechanism back and forth. When the guide block moves back and forth on the guide rail, the gear lever touches the matching rod on the driving block to rotate the driving block, and the driving block drives the intermittent gear to rotate. The intermittent gear meshes and connects to the flipping gear to rotate, and the flipping gear drives the processing block at the top to rotate. Therefore, when the top surface of the cover plate prefabricated mechanism is scraped back and forth, the processing block is rotated synchronously through the flipping assembly, and the concrete overflowed from the top of the cover plate prefabricated mold is scraped inward to reduce the occurrence of overflow.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The present invention improves the structure of the existing concrete track cover by arranging cross ramps at both ends of the track-bearing base of the track cover body and opening a rail sleeve at the bottom of the track-bearing base, so that the track cover body can ensure the track protection while improving the functionality, which is convenient for railway construction vehicles to cross the track horizontally without damaging the track. In addition, rows of hanging holes are symmetrically opened on the rail-bearing base, which have the effect of drainage and moisture prevention and are convenient for hanging and installation. A number of anti-skid grooves are also opened on the inner wall of the rail sleeve, which is convenient for the later installation of anti-skid washers, further playing the role of protecting the track. The present invention also designs a track cover prefabrication device with high efficiency and production quality, which is conducive to saving labor resources and improving the production level and efficiency of the device.

[0030] 2. In the present invention, a driving gear is arranged at the bottom end of the mounting through hole. When the driving gear is driven to rotate by an external driving mechanism, the driving gear meshes with the opposing racks on both sides, so that the two opposing racks move in opposite directions. The opposing racks drive the linkage rod to move. The linkage rod pulls the molding block to move on the interlaced through groove. The molding block drives the second inclined surface to move, squeezing the internal space of the prefabricated groove to form a long-size controllable cross-ramp portion, so that the appropriate size can be selected according to production needs to prevent multiple sets of molds from increasing costs.

[0031] 3. In the present invention, a limit rod is arranged on the inner wall of the installation through hole. When the driving gear rotates, the rotating cylinder at its top is driven to rotate. The curved groove provided on the outer wall of the rotating cylinder is slidably sleeved on the limit rod. Therefore, when the rotating cylinder rotates, due to the cooperation of the curved groove and the limit rod, the rotating cylinder as a whole rotates and moves upward, and the rotating cylinder is lifted up to drive the annular groove and the top extension rod to move upward. The top extension rod moves upward and is inserted into an axial hole vertical to the double-axial hole. The top extension rod squeezes the support rod, and the contact surface of the top extension rod and the support rod is in the shape of a hemispherical head. The support rod is movably inserted into an axial hole horizontal to the double-axial hole. The movement of the support rod drives the compression plate to move, and the compression plate slides in the limit groove to squeeze the spring. The other end of the support rod extends out of the row and hanging block to form a bulge. After the recycled aggregate high-performance concrete is poured, when the steel frame is placed in it for solidification and fixation, the raised support rod gives the steel frame a supporting force to prevent the steel frame from sinking to the bottom, which is beneficial to improving the prefabrication quality of the track cover.

[0032] 4. In the present invention, a mounting block is arranged at the output end of the vertical moving mechanism, and a servo motor is arranged on the mounting block to drive the servo motor to rotate. The servo motor drives the rotating disk A to rotate, and the rotating disk A pulls the belt to drive the rotating disk B to rotate through the connecting rod. The rotating rod on the rotating disk B pulls the guide block to slide back and forth in the guide rail, driving the flip assembly to scrape the top surface of the cover plate prefabrication mechanism back and forth, smoothing the recycled aggregate high-performance concrete in the cover plate prefabrication mechanism, further reducing manual intervention while improving the quality of the track cover plate prefabrication process.

[0033] 5. In the present invention, a shift rod is provided at one end of the guide rail. When the guide block moves back and forth on the guide rail, the shift rod touches the matching rod on the driving block to rotate the driving block, and the driving block drives the intermittent gear to rotate. The intermittent gear meshes and connects to the flip gear to rotate, and the flip gear drives the processing block at the top to rotate. Therefore, when the top surface of the cover plate prefabrication mechanism is scraped back and forth, the processing block is rotated synchronously through the flip assembly, and the concrete overflowed from the top of the cover plate prefabrication mold is scraped inwardly, which reduces the occurrence of overflow, saves raw materials, saves labor, and further reduces the prefabrication cost.
